Yes, I think at least for the moment it should work fine this way.
Eventually, I'd like to integrate it with --export (and associated QMP
commands, which are still to be created), too. Maybe at that point we
want to make the QOM object not user creatable any more.
Would it make sense to prefix the object type name with "x-" so we can
later retire it from the external user interface without a deprecation
As for test cases, do you think it would be hard to just modify the
tests to send an explicit 'quit' command to the daemon?

It's the next thing I'm planning to work on after completing the
coroutine-base QMP handlers (which I hope to get finished very soon).
For the time being I would suggest that you put any patches that depend
on qemu-storage-daemon (if you do need it) at the end of your series so
that we could apply the first part even if the storage daemon isn't in
The latest version of my patches is at:
But if you just need something for testing your code, I think it would
even make sense if you kept your standalone tool around (even though
we'll never merge it) and we'll deal with integration in the storage
daemon once both parts are ready.
